ROOFING.

SPECIFICATION forming part of Letters Patent No. 394,450, dated December 11, 1888.

Application filed September 24, 1888. Serial No. 286,270. (No model.)

To all whom it may concern:

Be it known that I, OTTO BOKLEN, a subj ect of the King of \Viirtemberg, and a resident of Stuttgart, in W'iirtemberg, Germany, have invented a new and useful Improvement in Roofing, of which the following is a specification. 7

This invention relates to roofing or like construction composed of separate plates, whether plane or corrugated metal plates, tiles, slates or other plates, rectangular or of other shape, all of which are intended to be hereinafter expressed and included in the term plate or roofing-plate.

The improvement consists in the mode of fastening the same, its Object being a simple fastening, enabling a whole roof fastened in the improved manner, or any single plate or plates thereof, to be built up, inserted, or removed without difiiculty by an inexperienced person.

Reference being made to the accompanying drawings, Figure 1 is a vertical section of a portion of roof constructed with plates fastened in the improved manner. Fig. 2 is a rear elevation of one of the plates, showing the clamp in full lines fastening the same to the purlin or horizontal cross-bar on which the plate is hung, and in dotted lines as detached from said purlin. Fig. 3 is a side view of Fig. 2. Fig. l is a side view of the clamp removed from the plate. Fig. 5 is a rear elevation of the plate with clamp turned up unfastened and forming a handle for convenient removal or insertion of the plate from or into its place in the roof. Fig. 6 is a side view thereof. Fig. 7 shows the pivoted pin fixed in a metal plate, and by which the clamp is attached thereto. Fig. 8 shows the said pivoted pin as attached to a clay plate or tile. Fig. 9 is a modification illustrating another mode of fastening the clamp to a metal plate. Fig. 10 is a plan view thereof. Fig. 11 is a sectional side view showing a clamp so fixed in position on the plate and purlin. Fig. 12 illustrates the method of attaching to a clay tile the spring which holds the clamp in the said modification.

In Fig. 1, D is a rafter. E E E are purlins or horizontal cross-bars supporting the plates, in place of fastening each row of plates to an upper purlin, and permitting it to rest upon or Over the lower row of plates fastened in like manner to the purlin next below. I fasten the plates by a movable clamp to the lower purlin, and cause them to rest back upon the purlin next above and underlap the lower edge of the row of plates next above, which are in like manner supported by clamps upon said upper purlin to rest upon the purlin next above the latter. This construction gives great security to the plates, downward sliding being prevented by the clamps attached to the plates, upward sliding by the clamps and plates of the row next above, outward movement of the top of the plate being restrained by the purlin and overlapping plates, and similar movement of the bottom of the plate by the clamp.

In order to enable each plate to be separately removed, the clamp holding the same is made revoluble to be freed from the purlin and enable the plate to be slid downward until free from the purlin next above, when it may be removed. Another feature of the clamp is that the same is itself removable for convenience in transport. Another feature is that the clamp is not visible from outside the roof, and therefore, also, does not form a ledge or projection for dirt, rain, water, 810., to lodge on.

The clamp is of the form shown in Fig. 4, having a face, 0, adapted to lie against the plate, an upward bend, 1'), equal to the thickness of the purlin, and a tongue, a, to overlap the purlin. The clamp is so fixed to the plate that it is revoluble about a center located within the limits of the face c. The location of this center on the plate will depend on the position of the purlin and the length of plate which is to overlap the row of plates next below. I prefer to pivot the clamp to the plate by fastening to the latter a headed pin, A, if a metal plate, riveted through it, as in Fig. 7, or if a clay tile, riveted or fastened to a plate, f, embedded in said tile before baking, as in Fig. 8.

In the face 0 of the clamp is a slot, (I, to enable the face to be slid under the pin A, as in Fig. 2. The face 0 is slightly curved to spring up under the head of the pin for holding the clamp in place by frictional resistance. A

feature in the clamp is the corresponding] hole, e, in each, so that the clamps may be strung together for convenient transport.

It will be understood that the distance between the pin A and the part b of the clamp is such that a sufficient distance is left between the purlin and the said part b, when the clamp is in the position shown in Fig. 5, to enable the plate to be removed from the purlin next above.

In place of the pin A and slot d there may be made in the clamp C a projection, i, Figs. 9, 10, and 11, and a spring-plate, B, may be fastened on the plate to overlap the clamp, having a corresponding recess, 1', to engage over the projection i in the clamp and hold the same in place. The spring B may be riveted to a metal roofing-plate at g, or may be attached to a clay tile or other roofing-plate not suitable to be riveted by engaging in the slot formed by the two projecting bars h 7L, formed on said tile, as in Fig. 12.

I claim 1. The combination, with a roofing-plate, of a clamp, O, revolubly attached to said plate and adapted to engage upon a purlin, substantially as set forth.

2. The combination, with a roofing-plate, of a headed pin, A, fastened thereto, a removable clamp, 0, having a slot, d, adapted to engage on said pin, so as to be revoluble thereon for attachment of said plate to a purlin, substantially as set forth.

3. The combination, with a roofing-plate, of a headed pin, A, fastened thereto, a removable b yonet-clamp, 0, having a curved face, 0, and a slot, (1, in said face, substantially as and for the purpose set forth.

4. In a roofing-construction, the combination, with a frame having purlins E E E, of a series of overlapping rows of roofing-plates,

the upper edge of each row resting without fastening against a corresponding purlin, and rotary clamps 0, attached to said plates and embracing the purlin next below, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

OTTO BOKLEN.
